I met a fellow vet who'd been in the Army. I was in the Navy, and aboard a minesweeper as a radioman among several assignments. I was surprised to learn that this Army guy, who was retired from the service, had been the skipper of an Army tug boat! Who knew? That seemed like an unusual Army career indeed, apparently around ports handling Army supplies including provisions and ammo transported by ship and barges. Any unlikely service histories, either yours or others that you've heard of?
